Quality Control

Our production of this copolyester adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, acid value, thermal transition temperatures, and monomer content are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This polymer is hygroscopic (moisture-sensitive); keep the original container sealed to prevent moisture absorption which can affect processing and final properties.
